-THILL-COUPLING.

EPECIFICATIQN forming part of Letters Patent No. 362,753, dated May 10,1887.

Application filed March 10,1887. Serial No. 230,365. (No model.)

To all whom it may concern.-

Be it known that I, WARREN H. Looms, of Fulton, in the county of Oswego,in the State of New York, have invented new and useful Improvements inThin-Couplings, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

This invention relates to the class of thillcouplings in whichcoupling-lugs formed intogral with the ears of the clip-tie enter intothe eye of the thill-iron; and the invention consists in an improvedconstruction and combination of parts, as hereinafter fullydescribed,and set forth in the claims.

In the accompanying drawings, Figure 1 is a side view of my improvedthill-couplin Fig. 2 is an inverted plan view of the same. Fig. 3 is avertical transverse section on line 00 at, Fig. 2. Fig. 4 isa view ofall the parts detached; and Fig. 5 is a side view taken at the side ofthe movable jaw of the coupling.

Similar letters of reference indicate corresponding parts.

0 represents the clip, which strides the axle A and is secured theretoby the clip-tie D in the usual and well-known manner. Said cliptie isformed with lateral projections ltl'l, in front and rear of the axle andflush with the under side thereof, as shown in Fig. 5 of the drawings.The front of the elip-tie is formed with the ear 6, and with the conicallug a on the side of said ear, which lug is provided with ascrewthreaded eye, I). On the rear projection, 11, is hinged ajaw, D,which is extended forward and terminates with an ear, 6', which has onthe side facing the other ear, 6, the conical lug a, provided with asmoothbored eye, I).

I denotes the thill-iron, formed with the eye I, which has its interiorshaped double conical, or flaring from the center of its length towardits ends, as shown in Fig. 3 of the drawings.

O O are conical washers composed of leather or other suitable material,which washers are introduced between the lugs a a and the interior ofthe eye I of the thill-iron, as shown in Fig. 3 of the drawings.

11 denotes the couplingbolt, which is inserted into the smooth eye ofthe lug a, and has its inner end screw-threaded and engaging thescrew-threaded eye Z) of the lug a, and serves to draw the lugs a atightly into the eye I, so as to effectually prevent the latter from rattling. Into the screw-threaded eye I) of the lug a, from the outer faceof the ear (2, is introduced a set-screw, h, which is to be screwed intosaid eye so as to cause the inner end of said set-screw to bear firmlyon the inner end of the coupling-bolt d, and thereby prevent thelatterfrom working loose, thus rendering the coupling very secure.

The elip-tie D is boxed on its upper side to form a recessed seat, a,with bearings t 1 against the front and rear of the axle, said clip tiebeing thus provided with a firm hold on the axle. The lateralprojections 11 n serve to support the hinged jaw D against upwardstrain.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. Ina thill-coupliug,the thill-iron provided with a conical eye, incombination with conical coupling-lugs connected to the axle-clip andadapted to enter into the eye of the thill-iron, one of said lugs havinga smooth eye and the other lug a screw-threaded eye, the couplingboltinserted in the smooth eye and engaging the screw-threaded eye, and asetserew inserted in the latter eye and bearing on the inner end of thecoupling-bolt, substantially as set forth.

2. In combination with the clip O, the cliptie D, formed with thelateral projections n n in front and rear of the axle and flush with theunder side thereof, and formed also with the ear 0 and the conical lug aon said ear,

said lug being provided with the screwthreaded eye b, the jaw D, hingedon the cliptie and formed with the ear 6, and the conical lug a, havinga smooth eye, I), the thill-iron I, having the double conical-shaped eyeI, the conical washers c c, the coupling-bolt d, inserted through thelug c and engaging the eye of the lug a, and the setscrew 71, insertedin the latter eye and bearing on the inner end of the coupling-bolt,substantially as described and shown.

In testimony whereofl have hereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Fulton, in the county ofOswego, in the State of New York this 7th day of March, 1887.
